The invention provides a method for measuring the speed of a train. The method for measuring the speed of the train includes the steps that S1, the speed measuring value of radar in a first speed measuring system and the speed measuring value of a speed sensor in the first speed measuring system are fused so as to obtain a fused value, and the first speed measuring system is arranged at one end of the train; S2, the fused value is voted to obtain the speed measuring result of the first speed measuring system, the speed measuring result of the first speed measuring system is transmitted to a second speed measuring system, and the second speed measuring system is arranged at the other end of the train; S3, when radar in the second speed measuring system is ineffective, the second speed measuring system judges the effectiveness of the speed measuring value of a speed sensor of the second speed measuring system through the speed measuring result of the first speed measuring system. On the premise of guaranteeing security, usability of system speed measuring can be improved, and the defect that in a rail transit system, radar short-time speed measuring faults which are accidental and irregular lead to ineffectiveness of system speed measuring is well overcome.
